Wooden building bricks

Abstract

An interlocking building block comprising a solid body of wood including a pair of spaced brick-shaped portions rigidly interconnected by a similarly shaped intermediate portion.

What is claimed is: 
     
       1. An interlocking corner building block comprising a solid body of wood including an exterior portion of generally L-shaped configuration in plan, a spaced interior portion of generally rectangular shape in plan and an intermediate portion rigidly interconnecting said exterior and interior portions, said exterior portion having generally planar intersecting exterior surfaces of rectangular configuration facing in directions which are perpendicular with respect to each other, said rectangular exterior surfaces having equal coextensive heights measured in the direction of intersection, one of said rectangular exterior surfaces having a length generally twice the length of the other, said exterior portion having parallel planar side surfaces extending inwardly along the length of said exterior surfaces and two planar end surfaces one of which extends inwardly of the free end of said one rectangular exterior surface in parallel relation to the other rectangular exterior surface and the other of which extends inwardly of the free end of the other rectangular exterior surface in parallel relation to said one rectangular exterior surface,   said interior portion having a planar surface disposed within a plane common with said other end surface of said exterior portion, a planar end surface disposed in a plane common to said one end surface of said exterior portion, a first groove side defining surface disposed in parallel relation to said end surface of said interior portion and facing in the opposite direction and parallel side surfaces disposed in parallel planes common to the side surfaces of said exterior portion,   said intermediate portion having parallel rectangular planar surfaces disposed in abuting alignment with said parallel planar side surfaces of said exterior portion, said intermediate portion providing an L-shaped tongue of rectangular cross-sectional configuration between the end surface of said interior portion and said one end surface of said exterior portion and two common adjacent side surfaces of said exterior and interior portions and a first complementary groove of rectangular cross-sectional configuration between the other two common end surfaces of said exterior and interior portions,   said first complementary groove being open at one end and defined at its other end by an end wall disposed in general alignment with one end of said L-shaped tongue and in intersecting relation with the associated rectangular planar surface of said intermediate portion, the bottom of said first complementary groove being defined by a surface disposed in aligned relation with the opposite end of said L-shaped tongue,   said exterior portion having a second groove side defining surface disposed in parallel relation with and facing toward said first groove side defining surface, said intermediate portion having a groove bottom defining surface disposed in parallel relation with the planar surface of said interior portion and intersecting at its ends with the rectangular surfaces of said intermediate portion and at its sides with said first and second groove side defining surfaces so as to define therewith a second complementary groove of rectangular cross-sectional configuration open at both ends,   said exterior portion being formed with a beveled peripheral surface between said exterior surfaces and the end and side surfaces thereof.
